Apple has yet to reveal when the new devices will go on sale, although last year sales of the iPad 2 began nine days after the launch, which also took place in March.

The iPad 3 is expected to have a sharper resolution screen than its predecessor, along with support for wireless carriers’ fourth generation LTE networks, The Wall Street Journal reports. Wireless carriers including AT&T and Verizon Wireless are expected to sell the new model.
